At present, the shelter has survived the disaster three times in total. Counting the two live broadcasts, it ranks first. Multiplied by two, it adds up to five times.

Previously, in the time relics, sumo has completely detected the number of disasters needed for upgrading by using the core of Magu.

At present, upgrading LV3 of underground shelters requires three times of disaster relief, and upgrading lv4 requires five times according to this range, which is just right!

If the next disaster can also reach the top ten in the world, seven upgrades of LV5 can also meet the conditions.

"It's not too late. It's better to hit the sun than to choose a day. Start upgrading now!"

Click on the four little girls who have fallen asleep at this time. Looking at Moore who just came to the first floor and immediately lay down and slept, Su Mo smiled and thought out of the game panel.

On the upgrade page, all conditions, including the building requirements on the ground and underground, have been met at this time due to the card bug.

Under various conditions, the upgrade button emitting golden light is just like that in krypton gold web game. It's almost shouting: if it's a brother, come and order me!

For this situation, after repeatedly confirming that there was no other consumption, sumo naturally did not give in, and the idea quickly gathered and formed, heavily hitting the upgrade button.

1000 disaster points are deducted instantly. In the next second, the familiar earth and mountains are "blown up" again.

WOW!

WOW!

The floating soil floating on the ceiling began to fall down with the shaking, and the underground refuge seemed to wake up again as those sleeping gods, "heartbeat" gradually became stronger.

Breathe and breathe, very frequent, four small lying on the ground, also like a soft marshmallow, ups and downs.

"Well... Well, so comfortable!"

Holding the constantly shaking ground, Moore, lying on the ground and sleeping soundly, changed a more comfortable position, and didn't feel any danger in the presence of Su mo.

Even the alert Oreo, after being shaken up, just raised his eyes to see sumo standing in front of him, and then fell asleep.

As for the big and small sparks, as a stable chicken, this shaking is simply a sprinkling of water for the chicken. The whole two hours are not even bothered to open their eyes. It's a stable one.

"Trust me so much, I'm not afraid I'll sell it to you."

Shaking dizzy, sumo simply sat directly on the ground, leaning against Moore, slowly waiting for the upgrade and evolution.

Each upgrade is a new life for underground shelters.

Compared with the wake-up of Poseidon in the trailer, for the upgrading of underground shelters, the feeling that the gods want to recover is more serious.

It's like this shelter made of pure stone came to life at this moment.

Late at night, wait quietly.

After waiting for about ten minutes, with the emergence of the tortoise shell core of the underground shelter, when a light swept over it, all the shaking stopped abruptly, and the upgrade interface also lit up a strong yellow light.

LV3 shelter

It's done!

Compared with the earth shaking changes in the refuge like Lv2, the upgrade of LV3 is nothing special before the refactoring function is used!

There is no big change in the overall attribute except for a new function - asylum.

At the same time, at the bottom of the page, the upgrade conditions of lv4 also jump out.

[underground shelter lv4 upgrade preview]

[condition 1: the main shelter has passed more than 5 disasters, and the durability of the shelter shall not be less than 50% at the end of the disaster. (entering the top ten times in the world automatically +1) (reached)]

[condition 2: the number of one star resources and half star resources within the main shelter reaches one (reached)]

[condition 3: the underground part of the shelter can be upgraded only after the safety assessment score reaches 15 (current: 328; achieved)]

[condition 4: the above ground part of the shelter can be upgraded only after the safety assessment score reaches 30 (current: 227; achieved)]

[condition 5: the shelter needs to have a growth potential item in order to upgrade (at present, it has: workbench, micro oil well, Youneng well, small thermal weapon laser manufacturing machine tool, large vegetable culture medium, furnace)]

[condition 6: pay 2000 disaster points for upgrade (2000/11012)]

[preview of new function: remote repair (when the shelter owned by the player is damaged by external damage, the game panel will remind according to the current durability of the shelter. Within a certain range, the player can also provide materials and disaster points for durability recovery. The lower the durability, the higher the recovery needs]

[preview of new function: solid (the durability of an item belonging to the designated shelter is bound to the shelter gate. Before the durability of the item is not reset to zero, and before the durability of the gate is 50% of the durability of the shelter, it is invincible by default and cannot be broken by any external force)]

[preview of new function: reconstruction times +1]

"Hey, I've met all the upgrade conditions of the level 4 shelter. This is the advantage of being ahead of everyone. As long as I have enough disaster points, I can upgrade mindlessly!"

The green completion sign behind the upgraded conditions of all level IV shelters is the affirmation of sumo's long-term hard work.

If there is no previous accumulation, it will be extremely difficult to see this upgrade condition at first sight.

Not to mention how difficult it is to get 2000 points in today's environment.

Say one and a half star resources, which is difficult for 99.9% of the people in the world.

In addition to the real European emperor, or came near the previous resource points as soon as he was born.

If you want to get these conditions together, you have to wait for the waste soil for at least half a year, or a year before it is possible.

As for the score of the rear safety assessment, these two items click on the scoring rules given by the system. After a little check, Su Mo understood the source of the score.

"If you still have requirements for this score in the future, you can try to find a loophole!"

In the calculation of score, each rifle in the weapon warehouse of the underground shelter can provide a score, with a maximum of 50 points.

There are also a lot of explosive bags. A explosive bag has 5 points, and the upper limit is 100 points.

But this is not a big head. It can be used to monitor the big ass TV outside. It actually accounts for a full 100 points in the score.

The gate of the garage on the first floor is only in its early 50s.

From this point of view, if the scores on the ground and underground are not enough in the later stage, we can get together and drill holes by moving things.

After a survey, for the new functions of level 4, Su Mo had already checked in advance after integrating Magu's refuge core into the time relics.

At this time, there was no surprise. After the mind fretted, the upgrading of the level 4 shelter also began to proceed vigorously.

With the previous foreshadowing, this level 4 upgrade did not cause any big "waves".

After shaking for about 20 minutes, the upgrade was over, and the whole shelter returned to its usual calm.

At the same time, as a small milestone, the LV5 shelter upgrade preview finally jumped out. Just looking at various conditions, Su Mo took a cold breath.

[underground shelter LV5 upgrade preview]

[condition 1: the main shelter passes through more than 7 disasters, and the durability of the shelter shall not be less than 50% at the end of the disaster. (entering the world's top ten times automatically +1) (7/5)]

[condition 2: after reaching lv4, kill more than 500 enemies of other races (500/0)]

[condition 3: Players' overall physical fitness score needs to reach more than 50 points (current: 42)]

[condition 4: the main refuge needs to have an extraordinary blessing, and the level of blessing cannot be lower than LV1]

[condition 5: players need to enter the relic more than five times, and the relic level cannot be lower than level 1 (5/3)]

[condition 6: pay 3000 disaster points for upgrade (3000/9012)]

[preview of new function: Tianjiang red envelope (randomly obtain a modular article drawing and several kinds of drawings need materials)]

[new function Preview: Refactoring]

"Hiss“

"No wonder Magu's shelter has been through more than a dozen disasters, and it has only been upgraded to LV5. From now on, the difficulty is just beginning!"

Seeing the requirements of LV5 level and the new functions after upgrading for the first time, Rao was determined and couldn't help shaking in his heart.

Through these conditions and functions, sumo has finally clarified some of the mysteries of the previous deep-sea refuge.

"The oil well should be opened by Ma Gu from the red envelope of upgrading LV5, which also explains why he has such a good thing from the side."

"And the player's overall physical fitness score should actually reach 50 points. With my current physical fitness, it's still a full eight points worse!"

Compared with the soft requirements of lv4, it has become a very abnormal hard requirement since LV5.

You know, in terms of Su Mo's physical fitness, even a 100 kg bench press is not a problem.

The hard pull is up to 220 kg.

However, there is still a full seven points to meet the upgrading needs of LV5.

"According to the physical quality of the waste land per capita, if it weren't for the welfare disaster, for a long time, everyone couldn't even eat enough, and there was no physical fitness to upgrade the shelter. No wonder Magu had been upgraded to LV5 for more than a year."

"However, since the upgrading conditions of the shelter involve human quality, there will definitely be 70 points, or even 100 points in the future!"

There is a long way to go in upgrading.

Thinking of the various difficult conditions to face in the future, Su Mo had to keep all the requirements in mind, looked at the upgrade requirements of LV5, and resolutely closed the game panel.

"It won't take long. As long as I wait until the depression ruins are opened once, I'm only one time away from the ruins."

"Now, unlike before, disasters are frequent again. As long as I can find any relics on the sea, enter them and withdraw immediately, the conditions can be met immediately."

Calm down. For today's refuge, sumo decided not to make any changes before moving.

Just wait until tomorrow morning, choose the location, and get out the warehouse where the food is stored, even if it is the final preparation.

"After waiting so long, the design drawing of this destroyer is finally available!"

My heart moved, watching the lavender design of the destroyer jump out of my hand, Su Mo's hands slightly forced, 1000 disaster points spent at the same time, a rude memory hit my mind again!
